In the interval 0 to 90°,

- sin is an increasing function i.e. as the value of angle(Ф) increases, the value of   function sin(Ф) increases . So if A>B, then Sin A > sin B.
  So the statement  is true.

- cos is a decreasing function i.e. as the value of angle(Ф) increases, the value of   the function cos(Ф) decreases. So if A>B, then cos A < cos B.
  So the statement is false.
